<Value> The transferred value (1, 2 or 4 data bytes) depends on the
data type of the Object to be read or written (see section

Note
Direct transfer of values via the serial interface with CI
commands always takes place in the basis system and
requires conversion into increments.
All parameters are always saved in increments in the con-
troller and are not converted into the relevant measuring
system until they are written or downloaded. All physical
variables (position, speed and acceleration) must be con-
verted into increment values before they can be trans-
ferred.
Further information on converting can be found in
section A.4.
